[SOLVED] The K key on my keyboard is being weird

[HeroYT]

About a week ago, the K on my keyboard stopped doing anything. I thought it was my old keyboard, but when I bought a new one it still wouldn't work. Combinations such as Shift + K and CTRL + K work, but K alone won't.

If you are using windows 10:
turn off "filter key" in ease of access under all settings.
If that doesn't work go to device manager and uninstall the keyboard drivers then scan for hardware changes.
